KNOTTING MECHANISM FOR IS'ELF-BINDERS.

SPECIFICATION forming part of Letters Patent No. 274,870, dated March 27, 1883.

1 Application filed June 28, 1882. (No model.)

To all whom it may concern Be it known that we,WILLIAM N. WHITE- ,LEY and WILLIAM BAY'LEY, of Springfield,

in the county of Clarke, State of Ohio, have invented a new and useful Improvement in the Cord-Guide and Stripper of -the Knotting Mechanism of Self-Binders, of which the following is a specification.

In the accompanying drawings, Figure 1 is a perspective view, shown partly in section,

of our improved combined stripper and cordguide represented as attached to the knottingmechanism-of a self-binder; and Fig. 2 is a sectional elevation of the cord-guide stripper of the same, drawn to a reduced scale.

This invention relates to self-binders that use cord as aband material, and a cord-knotter to secure the ends of the band; and it consists in an extension of the pivoted and oscillatory knot-stripper that at a time when the guide is in position to receive the cords stands across the slot made for the passage of the binding-arm in the overhanging bridge, said extensionforming an inclined guide to give proper direction to the cord and thereby insure its proper delivery to the knotter and gripper, as will hereinafter more fully appear.

ais an overhanging inclined bridge, suspended above the binding-table a in a suitable manner to separate the knotting mechanism b from the grain between it and said binding-table. y

c is a metallic frame, to which the knotting mechanism is secured.

dis a slot made in the bridge a for the passage of the point of the binding-arm d, carrying the ends of the binding cord e to the gripper f. The knotter-wheel h is provided with teeth h at a suitable part of its face i to insure a proper meshing with the pinion 1, that turns the knotter b one revolution for each knot made in the band material.

m is the stripper, pivoted at n to a frame, 0, and receivingan oscillatorymovementthrough the agency of a cam,c-, formed upon the wheel h and engaging with the end 12 of said stripper. This oscillatory movement is imparted to said stripper to cause the notch q, through which both ends of the band material pass on their way to the gripperj, to remove the knot from the hook I) after said knot has been properly formed and the encircling band cut loose from its supply. The extension 1' of the stripper m performs an important duty in giving direction to the cord and absolutely preventing it from falling between the bridge a and the under side of said stripper. It will be observedthat this extension, combined with the overhanging bridge, forms an inclined chute with a flaring mouth for the reception of the cord, which will, when the cord is otherwise imperfectly directed by foreign matter, slide down said extension andsuitably rest upon the face of the knotter-hook b for the proper formation of a knot in the ends of the band material.

Having thus described our improvement, what we claim as new, and desire to secure by Letters Patent, is-- 1. An oscillatory cord-guide and stripper pivoted to the knotter-frame, and actuated as specified, and provided with stripper-notch q, and the extension i, which forms an inclined chute into the mouth of and to the bottom of the notch in said stripper, for the purpose set forth. i

2. An oscillatory cord-guide and knot-stripper pivoted to the knotter-frame, said strip-' per-arm having the stripper-notch q, provided with the extension 7, which forms an inclined chute into the mouth of and to the bottom of the notch q, combined with the slotted bridge a, interposed between said stripper and the sheaf, the extension arranged to stand across the slot, substantially as described, and for the purpose set forth. 7

In testimony whereof wcfhave hereunto set our hands and affixed our seals this 17th day of June, 1882.

WILLIAM N. WHITELEY. WILLIAM BAYLEY. In presence of- HENRY MILLWARD, E. 0. BOWMAN.
